I started out with Dillon on the recommendation of a trusted friend. Over the years I've accumulated quite a collection of Dillon reloading tools, some great, some totally unnecessary.
I realize that many take issue with the fact that Dillon commands top dollar for their products. However, every single problem I've had with my press (a 550), which I have owned for 23 years now, they've either fixed it or sent me the replacement parts to fix it myself. The only thing they've asked was, "Do you need anything else?"
About two years ago ago my lovely bride decided she wanted a collection of that most valuable of all sea glass, red glass. She asked me if she could use my CV-2000 (the old model also 23 years in service). She wanted to use fine sand as a media and tumble some broken red bottle glass and short-cut Mother Nature. In went the the high quality, purest sandbox sand Lowes had to offer and on went the vibrator. This was about 10 PM and the sound was irritating as the devil so I left the shop for the night. We estimated it would take a day or more to get that lovely frosted look she wanted and I stayed away from the shop. Big Mistake.
When I went back about two days later the whole shop was covered with a fine silica dust and there was a cloud in the air. I put on a respirator and went in and shut off the tumbler. The sand inside the bowl had seized up solid as a brick. My wife grabbed a container of water and before I could stop her poured it in to "loosen up" the sand. What a mess.
Cleaned everything up (but I still find that silica in nooks and crannies), threw out the sand and glass (it didn't look any different than when it went in), and got my shop back and operational.
To my surprise that tumbler went right back to work - damn things are near bullet proof. After about a month of running brass through it, the motor shaft bearing gave out - the motor still ran but the shaft wouldn't turn. The fine abrasive had finally beat the 2000.
I emailed Dillon hoping I could just replace the motor assembly. They wrote back and said they had a different supplier now and besides that motor was no longer manufactured. But they asked what the problem was. I mea culpa'ed and told them the whole story (including the water dump). They said send us the old one and $75 and we'll ship a new one to you right away! Five days later I was back in business with a new CV-2001.
I bought a cheapie electronic scale from Cabelas, and while its okay, I find that I much prefer my Dillon balance beam for checking and weighing charges.
I've been using the SuperSwager for a while now as well - easiest way I've found of consistently taking care of primer pocket issues.
I have expanded out to other reloading tools from other companies, but I will always look to Dillon as a first option. They make fine tools, that are expensive, and they stand behind them.
